Outdoor Boilers

NOTE: The boiler shall be installed in a space large in comparison to the size of the boiler. Large space is defined as having a volume at least sixteen (16) times the total volume of the boiler.

These boilers are design certified for outdoor installa- tion. Boilers must not be installed under an overhang within three (3) feet from the top on the boiler. Three

(3)sides must be open in the area under the over- hang. Roof water drainage must be diverted away from the boilers with the use of gutters.

The point from where the flue products exit the boiler must be a minimum of four (4) feet below, four (4) feet horizontally from or one (1) foot above any door, win- dow or gravity inlet to a building. The top surface of the boiler shall be at least three (3) feet above any forced air inlet, or intake ducts located within ten (10) feet hor- izontally.

High-Wind Conditions (Outdoor Units Only)

In areas where high winds are frequent, it may be nec- essary to locate the boiler a minimum of 3' from high vertical walls, or install a wind break so the boiler is not in direct wind current.

Combustion and Ventilation Air (Indoor Units Only)

The boiler must have both combustion and ventilation air. Minimum requirements for net free air supply openings are 12 inches from ceiling for ventilation and 12 inches from the floor for combustion air as outlined in Z223.1 - latest edition or the current CAN/CSA B149, as well as any local codes that may

have jurisdiction.
